I have a Windows 7 32bit workstation that has no Internet Connection. This has only happened after the Windows 7 SP1 was installed. If I do a ipconfig I get the following result with no IP address -

Windows IP Configuration

I have seen this before on a XP workstation and I ran a "netsh winsock reset" command and it was able to resolve it. This is not the case with my current problem. I tried to do a restore but all my restore points are gone since the service pack update.

Any ideas how I can resolve this issue? Let me know if you require any additional information.

Make sure you have the correct drivers installed (NIC, Chipset etc.).

I know this sounds really, really simple but have you tried the Windows 7 network diagnostics tool?

Latest drivers are installed and I've tried the diagnostics tool but no joy.

As Rindi suggested, might be issue with your NIC, try to look in device manager and see if you can see any problems. Try to uninstall and reinstall NIC.

Can you set static ip address on your NIC and ping your gateway?
Let me know what the results are.

Could you post screenshot or full output of your ipconfig /all ?
Thanks.

I've uninstalled and reinstalled the NIC but still the same problem.

I've tried to assign a static IP address but it will not give me the "Properties" option. The only option I have is "Install"

I have ran the ipconfig /all command and I receive the following -

Post a screenshot of the device manager. To me it looks as if there is no physical NIC available.

And what is shown when you open the network and sharing center, then select Change adapter Settings?

try disabling all network cards except the broadcom one, check that your network cable is inserted in the right ethernet port.
Restart the machine, see the results.

I've disabled all network cards except for the broadcom and restarted. No difference.

Are you sure it isn't a virus or spyware issue?  Have you run Malwarebytes?

I meant the view before that, is the adapter "Enabled"?

Have ran a Malwarebytes scan and it's clean.

Yes, the adapter is enabled.

Try deleting the adapter from device manager, then restart the PC and allow it to install it again, then try getting a connection.

To me it still looks like malfunctioning NIC or incorrect drivers. Can you replace NIC to rule out this option, you might save yourself alot of trouble before we blame software settings.

Can you try to allocate NIC to another slot too if possible, just in case there is something wrong with motherboard.

Assuming your hardware, drivers are ok, it look like Service pack uninstalled your TCP IPV4.
Looks like it needs to be reinstalled.

Click on Internet Protocol TCP / IPv4.
If you see Install then click and choose Protocol, Add, choose Have Disk.
browser to c:\windows\inf and then click OK.
On the list choose Internet Protocol (TCP/IPv4), hit OK and you might need to restart.

In Device Manager>View, and check "Show Hidden Devices">Expand "Non plug and play drivers". Anything there with a problem?

Also, in the Event Viewer>Windows Event Logs>System, do you see any errors from the source "Service Control Manager"? Might be something like the AFD/IPSec driver not starting.....

Ok, I've added a USB NIC card to the system and installed it but getting the same result. The NIC appears to be installed correctly but if I do an ipconfig the results are blank. I think the original drivers for the NIC card are fine and the NIC card is working but the problem exists with the TCP/IP protocol.

I also tried to install the TCP/IP protocol but I cannot find the "inf" file in the Windows directory. Could it be somewhere else?

Do you have other devices running on your home network?

Do you have activity or connection lights on the back of your NIC?

Can you use static IP information?

Other devices on the network are fine.

Have link lights on the back of both NICs as both are now connected.

Cannot add static address as I do not have the option to go into properties on either NIC.

In your doc client for windows is selected.

I take it when you select IPv4 properties is also grayed out?

When you open properties of you connection does an error warning you of access restrictions appear?

I just checked on my Windows 7 64bit and I got the inf files present.

Just do exactly same thing as before but make sure to navigate to:

c:\Windows\inf\choose any *.inf file and press ok, Windows will give you option to install the protocols.

You need to run sfc /scannow from an administrator command prompt. Reboot and your network should be restored. Also on the back of the pc are the NIC lights on?
